RAILROAD-SWITCH.

SPECIFICATION forming part of Letters Patent No. 451,507, dated May 5, 1891.

Application iiled December 17, 1890. Serial No. 375,025. (No model.) v

To @ZZ whom t may concern.-

Be it known that I, WILLIAM R. MCGIBONY, a citizen of the United States, residing at Monroe, in the county of Walton and State of Georgia, have invented a new and useful Railroad-Switch, of which the following is a specilication.

This invention relates to railroad-switches, and more especially to that class of switches in which a pivoted frog-plate is operated automatically simultaneously with the switchrails.

The invention consistsin the improved construction and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, Figure 1 is a plan View of a railroad-switch constructed in accordance with my invention. Fig. 2 is a perspective detail View of a pivoted frog and its supporting-plate. Fig. 3 is a transverse sectional view of the frog and the supportingplate, taken on the line 3 3 in Fig. l. Fig. 4 is a detail plan view of the frog removed from its supporting-plate.

Like numerals of reference indicate like parts in all the-igures.

1 1 designate the main-line rails, 2 2 the siding-rails, and 3 3 the pivoted switch-rails, which are connected in the usual manner by the bridle-bars et. At the junction of the inner main-line rail with the inner siding-rail is arranged a supporting-plate 5,- npon which is mounted the pivoted frog 6. The latter is provided at its sides with longitudinal laterally-extending iianges 7 and the supportingplate on its upper side with longitudinal undercut flanges 8, adapted to form seats for the iianges 7 of the frog. The pivoted end of the latteris rounded, and the sideY flanges 7 are extended partially around the heel end, so as to be permanently seated in the undercut ianges of the supporting-plate. S uitable supports are provided adjacent to the top for a pair of T-shaped levers 9 9, the arms of which are connected by the rods 10 10. The laterally-extending arm of one of said levers is connected by a rod 11 with one of the pivoted switch-rails, and a rod 12 connects the laterally-extendin g arm of the other lever with the pivo-ted frog. It will thus be seen that when the switch-rails are adj usted the pivoted frog will be simultaneously thrown into position to open the main line or the siding, as the case may be.

The supporting-plate 5 is provided with a spacing-block 15, having undercut recesses 1G to receive the ends of the rails 1 2 and to prevent said rails from being forced together.

Having thus described my invention, what I claim is- 1. In a railroad-switch of the class herein described,the combination, with the supporting plate having longitudinal undercut flanges, of the pivoted frog having longitudinal laterally-extending iianges adapted to engage the anges of the supporting-plate, said -pivoted frog being provided with a rounded and partially-flanged heel permanently seated in the undercut flanges of the supportingplate, substantially as and for the purpose set forth.

2. In a railroad-switch of the class herein described, the combination, with the supporting plate having longitudinal undercut lian-ges and a spacing-block l5, provided with undercut recesses 16, of the pivoted frog having longitudinal laterally-extending iianges adapted to engage the iianges of the supporting-plate, said -pivOted ,frog being provided with a rounded and partially-flanged heel permanently seated in the undercut anges of the supporting-plate, and the rails 1 2, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.
